FILLING DEVICE FOR GREASE GUNS Filed Nov. 18, 1947 INVENTOR. Spa/war M/ Graham Patented Dec. 2, 1952 UNITED STATES PATENT OFFICE FILLING DEVICE FOR GREASE GUNS Spencer W. Graham, Grainfield, Kans.

Application November 18, 1947, Serial No. 786,625

2 Claims. (01. 226-429) My invention relates to a device for filling grease guns from cans or the like.

An important object of the invention is to provide a device of the above mentioned character which may be arranged within the can and submerged within the grease and connected with the barrel of the grease gun.

A further object of the invention is to provide a device of the above mentioned character which will withdraw the grease from the bottom of the can, and may be tilted so that its intake end may be brought into close relation to such bottom.

In the accompanying drawings,

Figure 1 is a central vertical section through a filling device embodying my invention, showing the same in use,

Figure 2 is a side elevation of the device removed,

Figure 3 is a similar view at right angles to Figure 2, and

Figure 4 is a plan view of the device.

In the drawings, the numeral l designates a can holding grease II.

My filling device includes a vertical tube l2, which is preferably cylindrical, and this vertical tube has downwardly diverging inclined tubes l3, connected therewith, as shown. The numeral [4 designates a cup or coupling, preferably formed of molded rubber, having a reduced extension I5, held within the upper end of the tube I3.

A rocking support is provided for the tube I2, comprising a horizontal rod or foot l6, to which are secured diagonal rods l1 and I8, and a vertical rod [9. These parts are rigidly secured together by welding or the like. The rod ll has its upper end attached to the tube I2 by welding or the like, and the rod I9 has its upper end attached to the tube in a similar manner, and the rod 18 has its upper end welded to the tube l2. The rods l1, l8, and I9, and the foot iii are arranged in the same plane, which is at right angles to the plane of the diverging tubes I2. The foot l6 rests upon the bottom 20 of the can, and the intake ends of the tubes l3 are spaced from the bottom 20, and may be brought into close relation to the bottom, by rocking the device upon the foot I6.

Secured to the top of the tube 12 are handles 2|, projecting above the tube but confined within the can so that the lid of the can may be applied.

A grease gun is shown, comprising a barrel 22 within which is arranged a plunger 23, operated by a plunger rod 24, having a handle 25. The usual cap has been removed from the barrel 22, and the screw-threadedend of the barrel engaged within the cup [4.

The operation of the device is as follows:

The filling device is arranged centrally within the can Iii, Figure 1, and the foot 16 rests upon the bottom 20. The tube support is vertical and the intake ends of the tubes I3 are spaced from the bottom 26. The filling device is submerged in the grease II, in whole or in part. The barrel 22 is now secured within the cup or coupling l4, and the plunger 23 raised to prime the filling device, which is eifected when the grease starts to enter the barrel 22. The barrel may now be removed from within the cup l4 and the plunger 23 returned to the starting position, subsequent to which the free end of the barrel is again engaged within the cup It. When the plunger 23 is moved upwardly the barrel 22 will be properly filled with the grease. When the grease is low in the can, the support including rods l1 and I8 are rocked upon the foot 16, thereby bringing the lower end of the tube [3 in close relation to the bottom. The entire filling device may be rotated within the can, if desired. After the filling operation, the lid may be applied to the can and the filling device held therein for further use.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of same and that various changes in the shape, size, and arrangement of parts may be resorted to without departmg from the spirit of my invention or the scope of the sub-joined claims.

Having thus described my invention, what I claim is:

1. A filling device for grease guns adapted for removable insertion within a container holding a quant ty of grease, said device comprising an upstanding tube adapted to project upwardly within a container in spaced relation to the bottom of the container; means at the upper end of said tube adapted to sealingly couple one end of a, grease gun to be filled with the upper end of the tube; a pair of downwardly divergent, coplanar tubes respectively formed open at their opposite ends and having their upper ends communicatmg with and rigidly secured to said upstanding tube, the lower ends of said divergent tubes constituting inlets through which grease may be drawn from the container to fill said guns; and a plane, upstanding support rigid at its upper end with the upstanding tube, said support being disposed in a plane normal to the plane of the divergent tubes and equidistant from the lower.

ends of said divergent tubes, the support having its lower end adapted to rest upon the bottom of a container and extended below the lower ends of the divergent tubes, thus to normally position said lower ends of the divergent tubes above the container bottom, the support being adapted to be rocked upon said lower end thereof within and relative to the container so as to rock the entire filling device bodily within the container and thereby swing the lower end of either divergent tube from its normal position into closer proximity to said container bottom.

2. A filling device for grease guns adapted for removable insertion within a, container holding a quantity of grease, said device comprising an upstanding tube adapted to project upwardly within a container in spaced relation to the,

bottom of the container; means at the upper end of said tube adapted to sealingly couple one.

end of a grease gun to be filled with said upper end. of the tube; a pair of downwardly divergent, coplanar tubes respectively-formed open at their opposite ends and having their upper ends communicating with and rigidly secured to said upstanding'tube, the lower ends of said divergent tubes constituting inlets through which grease may be drawn from the container to fill said gun; and a plane, upstanding support rigid at its upper end with the upstanding tube, said support being disposed in a plane normal to the plane of the divergent tubes and equidistant from the lower ends of said divergent tubes, the support having a, straight, horizontal lower edge adapted to rest upon the bottom of a container and disposed below the lower ends of the divergent tubes, thus to normally position said lower ends of the divergent tubes above the container bottom, the support being adapted to .be rocked upon said lower edge thereof within and: relative to the container so as to rock the divergent tubes bodily within the container in their common plane, thereby to swing the lower end of either divergent tube from its normal position into closer proximity to said container bottom.
